What is happening?... DefaultDS?
Greetings Gurus!
I am having difficulty referencing the DefaultDS from a
client running outside the JBoss JVM. Any advice or examples would be greatly
appreciated. I am running JBoss version 4.0.5GA. I eventually want to load
and use the datasource in the client application. For simplicity of example,
I set up a default JBoss install. It seems that I do not have access
to anything in the java: context from outside the JBoss JVM. Are there
security constraints that need to be modified?
Here is my source code:
---
import java.util.*;
import javax.naming.*;
public class JNDI {
public static void main(String[] args) {
try {
Context ic = new InitialContext();
// Print the environment settings
System.out.println("Printing environment keys:");
Hashtable hash = ic.getEnvironment();
Enumeration keys = hash.keys();
while (keys.hasMoreElements()) {
Object key = keys.nextElement();
Object value = hash.get(key);
System.out.println(key + "=" + value);
}
// We can see several bindings, just not the ones we need
System.out.println();
System.out.println("Printing bindings in jmx:");
NamingEnumeration b = ic.listBindings("jmx");
while ( b.hasMoreElements() ) {
Object key = b.nextElement();
System.out.println(key);
}
System.out.println();
System.out.println("Get the default datasource:");
// Both of the following lines choke:
// b = ic.listBindings("");
// Context compEnv = (Context) ic.lookup("java:/DefaultDS");
}
catch (Exception e) {
e.printStackTrace();
}
}
}

The first few lines of output look like:
Printing environment keys:
jnp.parsedName=
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
Printing bindings in jmx:
invoker:
org.jnp.interfaces.NamingContext:org.jnp.interfaces.NamingContext@a4e743
rmi: org.jnp.interfaces.NamingContext:org.jnp.interfaces.NamingContext@4aeb52

The "listBindings" call throws the following stack dump:

I am certain that the DefaultDS is up and running since the out of the box
examples work, however they are all running inside JBoss. I have tried many
many things to no avail.

I really want to use JBoss, and eventually lend my support to the efforts
surrounding what appears to be an awesome project, but I am beginning to
have doubts in my choice as I have been trying to get this to work for
some time. What am I doing wrong?
I am completely confused. Please advise.
Thanks,
Randall
